Application filed June 1,

To all whom it may concern:

Be it known that I, MILTON S. DUNKEL- BERGER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Collapsible Slip-Ons, of which the following is a specification.

The principal object of my invention is to provide for advertising cards and other objects, a collapsible slip-on that not only enables them to be easily mailed or shipped, but to be readily secured on suitable sup ports for displaying them.

hen employed in the advertising field, my collapsible slip-on makes it possible for a designer to mail frequently to a user, a set of diiferent cards or other devices for easy attachment to, and removal from, the same supports. It is thus possible for the user to slip on a support which he retains, any number of display devices equipped with my improved collapsible securing means. This makes it possible to easily change the display without altering the suport.

P In the accompanying drawings, Figure 1 is a perspective view of a card equipped with my collapsible slip-on, mounted on a suitable support. Fig. 2 is a rear view of a movable arm secured by my slip-on to a supporting member. Fig. 3 is a view looking down upon a card equipped with my improved securing means, showing the supporting member in dotted lines. And Fig. 4: is a view of said card showing the tubular securing means in a collapsed condition.

Throughout the specification and drawings, similar reference characters denote corresponding parts.

Referring to the accompanying drawlngs, the numeral 1 designates a display card to the back of which there is glued or other- Specification of Letterslatent.

wisesuitably secured a collapsible tube 2 that is made of cardboard or other firm, yet flexible, material. While the tube 2 is shown rectangular in cross section, it may be made in any other shape without departing from the spirit of the invention. The collapsible feature of this tubular slip-on 2 enables a number of cards to be compactly packed for mailing.

When it is desired to display the card 1, the tubular slip-on 2 is opened out and easily slipped over a post or supporting member 3 mounted on a base 4. In Fig. 2 the display devlce consists of a movable arm 5 that projects beyond a coat edge 6. Secured to the rear portion of this arm 4 is one of the tubular slip-ons 2 that secures said arm to a reciprocating member 7 that moves it. My improved slip-on makes it possible for the card 1 or the arm 5 to be readily secured on, or removed from, their respective supports.

My improved collapsible slip-ens may be made in standard size for application to any advertising or other object which it is desired to readily mount upon, or remove from, a supporting element. They may be cheaply constructed in large quantities, and may be readily applied to the objects for which they are intended.

aving described my invention, I claim:

In a device of the type described, the combination with a base, of a standard projecting upwardly from its middle portion, a display card adapted to rest on said base, and a collapsible tubular member applied to the rear surface of said card, adapted to be slipped on said standard to hold said car in a vertical position on said base.

In testimony whereof I have hereunto set my hand this 29th day of May, 1920.
